Expeditions of Ron Brechlin, Viktor Synjaev, Mildred Márquez, Juan Machado, Oleg Romanov and other colleagues over the last five years in Colombia, Ecuador and Bolivia have resulted in significant collections of Pterophoridae Zeller, 1841. The article describes five new species: Singularia brechlini Kovtunovich & Ustjuzhanin sp. nov., Singularia sinjaevi Kovtunovich & Ustjuzhanin sp. nov., Singularia guajiro Kovtunovich & Ustjuzhanin sp. nov., Singularia tolima Kovtunovich & Ustjuzhanin sp. nov. and Singularia lesya Kovtunovich & Ustjuzhanin sp. nov.

Five new species of the genus Singularia Arenberger, 1988 (Lepidoptera, Pterophoridae). European Journal of Taxonomy 247: 1–11. http://dx.doi. org/10.5852/ejt.2016.247 Introduction Alucita walsinghami Fernald, 1898 was described in a different genus, Singularia Arenberger, 1988. Later, Gielis & Matthews (1994) described the genus Chocophorus and included in it three known species and two new for science: Aciptilia alternaria Zeller, 1874, Pterophorus carabayus Arenberger, 1990, Alucita leptochorda Meyrick, 1913, Chocophorus solisi Gielis & Matthews, 1994 and Chocophorus venedictoffi Gielis & Matthews, 1994. In a subsequent publication, Gielis (2011) described one more 1 European Journal of Taxonomy 247: 1–11 (2016) species, Chocophorus mayaensis Gielis, 2011. Gielis (2012) synonymized Chocophorus under the genus Singularia. The genus Singularia, widespread in South and Central America, comprises 12 species, including those described in the present paper: Singularia alternaria (Zeller, 1874), Singularia carabayus (Arenberger, 1990), Singularia leptochorda (Meyrick, 1913), Singularia mayaensis (Gielis, 2011), Singularia solisi (Gielis & Matthews, 1994), Singularia venedictoffi (Gielis & Matthews, 1994), and Singularia walsinghami (Fernald, 1898). The species of this genus mainly inhabit mountain forests. Material and methods Holotypes and paratypes of the species described are stored in the collections listed below. Preparation of genitalia is necessary for the identification of Pterophoridae Zeller, 1841. Dissections were performed using standard methods.

The female genitalia of the new species are similar to those of S. alternaria in the shape of the antrum and signum, but differ by the shorter and more narrow antrum, and the wider signum. Etymology The species is named after the prominent German entomologist Dr. Ronald Brechlin, specialist in Saturniidae and Sphingidae, organizer and member of the expeditions during which this species was collected. 2 KOVTUNOVICH V. et al., New species of Pterophoridae from South America Material examined Holotype COLOMBIA: ♂, adult, Valle del Cauca, Res.
